Prince William allegedly feels that “he has lost” Prince Harry following the release of his younger brother’s memoir, “Spare.” Accordingly, he is said to be “feeling pragmatic” about the entire debacle.

Express UK reported that the assertions were from Neil Sean after learning the claims from a “very good source.” As noted, he shared the matter with his audience in one of the latest videos on his YouTube channel, “Neil Sean’s Daily News Headlines.”

In the material, the royal commentator is said to have stated that the Prince of Wales “feels that he has done everything in his power, his absolute best, to advise and guide” the Duke of Sussex.

He noted, however, that the former working royal “decided to take his own advice,” causing the future King to feel “resigned to the fact that he has lost his younger brother,” adding that the royal disclosed it to “a very good source."

Sean continued that “this is about mistrust,” before saying, “even if he said let’s forgive and forget, William feels there will always be a nagging feeling that if he lets Harry in, their conversations could be made public down the line,” as per the publication.

In the same video, the royal commentator is also said to have added that Prince William focuses on his family with Kate Middleton.

The publication, in its report published Monday, quoted Neil Sean from the material, saying in part that the Prince of Wales “is focused on raising his three children with his wife Catherine.”

The claims come after Prince Harry dropped his highly anticipated memoir, “Spare,” which hit shelves earlier this month.

In his book, the former working royal made several claims about some members of the British Royal Family, including the Prince of Wales.

Despite this, though, the royals continue to remain silent about the matter. They, alongside Buckingham Palace and Kensington Palace, have not released any statement or comment about the book.

Nevertheless, a royal insider spoke to People and revealed what King Charles III and Prince William would supposedly feel about the Duke of Sussex and his memoir.

As claimed, the British Monarch and the future King would “be feeling betrayed” as “things that have happened to them, really personal things, are now played out in the public arena.”

The insider also pointed out that some of the stories he included in his book are “not [Harry’s] to tell.”

Another source, who is said to be a family friend, told the magazine, as well, which published the assertions on January 11, that “there are so many things that he didn’t need to say” in his memoir.
